Abstract

PCT No. PCT/EP94/00528 Sec. 371 Date Sep. 29, 1995 Sec. 102(e) Date Sep. 29, 1995 PCT Filed Feb. 24, 1994 PCT Pub. No. WO94/23563 PCT Pub. Date Oct. 27, 1994A pilot valve for controlling a pneumatically actuated main valve of a milking-system pulsator, has an electromagnet that it is alternately energized and de-energized displacing an armature back and forth between each end of a stroke. At one end, the armature seals an air-supply line and at the other end a vacuumizing line. The lines are accordingly alternately connected to a valve chamber, and the valve chamber communicates with the main valve through a control channel. The armature is connected to a diaphragm so as to provide axial guidance for the armature without friction. The diaphragm is made of resilient material and is interposed between the armature and the electromagnet such that, when the armature is at one end of its stroke, it seals off the air-supply line.

に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention is a pre-control valve for operating a pneumatically operated main valve provided in a pulsator for a milking device, wherein an electromagnet is provided, and the electromagnet is provided. The armature is alternately excited and demagnetized for the purpose of moving the mover between the two end positions.At these two end positions, the mover closes the air conduit and the negative pressure conduit. Alternately, whereby the air conduit and the negative pressure conduit are alternately connected to the first valve chamber,
The first valve chamber is connected to the main valve via a control passage and relates to a type in which the armature is connected to a diaphragm such that frictionless axial guidance of the armature is achieved.

The upper surface of the mover is provided with a suitable sealing member so that a closure of the air conduit is effected. Furthermore, the diaphragm is formed as a spring unit. This spring unit creates a very high resistance against the movement of the armature in the direction of the air conduit. In order to overcome such resistance, a high switching force is required.

に交互に接続するのには適していない。From German Utility Model Registration No. 9114953, a valve is known in which the armature is guided by a diaphragm. In such known valves, the diaphragm is provided on the mover on the side opposite to the electromagnet. When the electromagnet is excited, the mover is attracted toward the electromagnet. At this point, the mover is held by the residual magnetic force. As a result, a high switching force is required to overcome such a residual magnetic force. Furthermore, since such a valve can only control the flow of one medium, this valve is not suitable for alternately connecting a control passage to an air line and a vacuum line.

ような汚染物が沈着する恐れもある。In the case of the valve described in DE-A-224 50 69, the armature consists of a cylindrical pin. This pin is guided axially in the notch of the electromagnet and in an opening provided in the valve. As a result, it is impossible to avoid a frictional force that causes wear and causes an increase in the switching force. And with the mover,
Contaminants that lock the mover may be deposited between the guide surface of the mover and the surface guiding the mover.

とならない。これにより低廉な手段が得られる。The use of the diaphragm made of the elastic material allows the mover to move with a small force. The arrangement of the diaphragm between the mover and the electromagnet prevents the mover from being stuck on the electromagnet due to residual magnetic force. In this case, the diaphragm must be made of a non-magnetic material, for example rubber. Since there is no friction and the residual magnetic force is cut off,
The switching force is extremely small. No additional sealing member is required because the diaphragm can close the air conduit tightly. This provides an inexpensive means.

る。In an advantageous embodiment of the invention, the connection between the armature and the diaphragm is effected by means of an attachment provided on the diaphragm and a hole provided on the armature. This not only allows for a low-cost connection, but also eliminates the need for additional sealing members. This is because the attachment closes the vacuum line at one end of the armature.

Has an attachment portion 5. The attachment part penetrates completely through the mover 6 and connects the mover to the diaphragm 4. The vacuum line 7 with the valve seat 8 is closed by the attachment 5 at the end position of the armature 6. The diaphragm 4 has a flow portion 9. Via this passage, the air conduit 3 can be connected to the first valve chamber 10. The control passage 11 extends from the first valve chamber as a starting point. The diaphragm 4 has a seal ridge 12 on the peripheral surface. This seal ridge seals the first chamber 10 and the second valve chamber 13 in which the air conduit 3 opens to the outside air.

つの弁もしばしば設けられている。When the electromagnet 2 is demagnetized, the mover 6 moves to the illustrated end position. The attachment 5 closes the negative pressure conduit 7. Since the air conduit 3, the second valve chamber 13 and the first valve chamber 10 are now connected via the flow passage 9, the surrounding air flows through the control passage 11.
Through the main valve (not shown). On the upper surface of the diaphragm 4,
During the switching operation, the air flow and the generated atmospheric pressure act. Since this atmospheric pressure is higher than the pressure at the lower surface of the diaphragm 4, a pressure gradient occurs. This allows
The armature 6 is connected to the negative pressure conduit 7 irrespective of the mounting position of the valve 1.
In the direction of the valve seat 8. When the electromagnet 2 is excited, the mover 6 moves upward together with the diaphragm 4 and comes into contact with the electromagnet 2. In such a position, the air conduit 3 is closed by the diaphragm 4,
The negative pressure conduit 7 is opened. As a result, a negative pressure is transmitted from the negative pressure line 7 via the first valve chamber 10 to the control passage 11 and thus to the main valve, causing a new switching of the main valve.
Such a switch is performed by a milking bucket (Melk
It is performed in a predetermined rhythm to create an alternating pressure in the gap of the becher. In this case, the alternating milking cycle (Wech

けを交換すればよい。Since the diaphragm 4 has a sealing function at both end positions of the mover 6 and seals both valve chambers 10 and 13 against the outside air, only the diaphragm 4 needs to be replaced at the time of wear or aging.
